solenoid exchange from 750 to 650?!?!

My kz650 is in need of a new solenoid. I happened to find one off an 81 750h. I believe that most kz650 parts were standardized from '77 to '80 or '81, but I have no idea about interchanging parts between 650s and 750s. I did check parts diagrams on kawasaki.com and they look different with different P/Ns. Does anyone know if this one will/could work?
Thanks,

Even though they have diff part numbers, it could be as simple as the physical dimensions of them are slightly diff but functionally they are identical.

I'm picking up a '78 KZ650-D1A that I won on eBay a few days ago. And if it's as pooched as the pics lead me to believe, I just might be parting it out.
I'll send you a PM later today when I get back with it and let you know.
